Kathorn perhaps Hathorn

I have Robert Burnell, born 1669-1674, Boston, MA.An old Burnell Family history gives his first wife as "Kathorn" who died Sept. 9, 1673, leaving 2 small children.Can anyone verify if she was a Hathorn, and if so what was her given name?{Robert m. (2) Sarah Chillson after the death of his first wife).
